Who can witness a will?

Who can act as a witness for a will in Australia

A will witness is generally a person who watches the testator sign the will and then signs it themselves to confirm they saw it occur. This is a formal legal requirement in Australia, not optional.

Will witnessing generally exists to prevent fraud and to support the idea that the document reflects the testator's true wishes. When someone witnesses a will, they generally provide evidence that the testator signed the document of their own accord, with understanding of what they were doing.

There are specific rules about who can be a witness. Generally, a witness must be an adult (18 years or older), of sound mind, and present when the testator signs the document. Some people are disqualified from witnessing, including beneficiaries of the will, their spouses or de facto partners, and the executor (in some circumstances).

Witness requirements relate to a will's validity, and failing to meet these rules may render a will invalid. People sometimes note that the formalities relate to a will's validity from the beginning of the process. Many people choose professional help in relation to the formalities, including witness arrangements.

For people creating a will themselves, the valid will witness requirements are sometimes described as one of a range of matters discussed in relation to common mistakes, though how each factor is weighed depends on the circumstances. The rule exists partly because a signed will without proper witnesses may face challenges later, which can cause distress and delay for families.

Key points

• Witnesses must be adults (18 or over) who are of sound mind

• A beneficiary cannot act as a witness

• Correctly signed wills generally involve having the appropriate witnesses present.

• The witnesses generally see the testator sign the will, and the testator generally sees them sign as well.

• Some people regard independent witnesses as one approach commonly discussed in relation to those connected to the family.

• Witness arrangements are sometimes discussed in connection with the likelihood of future disputes, though how this plays out depends on the circumstances.

Common situations

People sometimes look into witness rules in situations such as:

• writing a will without professional help and wanting to ensure it is done properly

• You're unsure whether a particular family member can act as a witness

• You've inherited property or changed your financial situation and want to update your will

• You're concerned about a will you've already signed and want to check if it was witnessed correctly

• You have a blended family and want to avoid later disputes about the will's validity

• acting as an executor and looking into what makes a will valid

• Some people seek to understand the rules after being told a will might be invalid.

Incorrect witness arrangements can have significant consequences. For example, where a beneficiary witnesses a will, the will may become invalid or at least open to challenge. This can delay the distribution of an estate and create conflict among family members. In some cases, invalid wills mean assets are distributed according to intestacy rules rather than the testator's wishes.

Matters people sometimes weigh up

• Have you chosen witnesses who won't inherit from your will?

• Are your chosen witnesses over 18 and mentally capable?

• Will your witnesses be easy to locate if the will needs to be proved later?

• Could choosing family members as witnesses create a perception of bias or pressure?

• Have you explained to your witnesses why they're being asked and what the role involves?

• Should you use professional witnesses or a solicitor to oversee the signing?

• Are you aware of any reason a chosen witness might be legally unable to act?
